A line of speakers sporting concentric driver designed with the technology and performance of speakers costing significantly more? Sounds like every audiophiles dream come true, right?
The Elac Un-Fi series from Andrew Jones was unveiled last week at CES Las Vegas and the whole show was abuzz with how great they sounded regardless of the price. With bookshelf, center channel and floor standing models available, the Elac Uni-Fi's might just have the right combination of speakers for you.

That is a very interesting coaxial driver.
To it looks like the first modern resurrection of the Jordan Watts Mk III module. It has a 4" aluminum cone that looks to have the similar if not identical tractrix shape.
Here is a closer look at one of my MK III cones.
Coming from the UK Andrew Jones is bound to be aware of these drivers. The MK I appeared in 1959! In my view they are the most remarkable driver ever to see the light of day. They have been waiting patiently for modern manufacture to really get them consistent.
Unlike other full rangers these do not peak and have a rising response. They have a slight roll off stating around 6 KHz. So when you do add a tweeter to these driver, the crossover is 1 cap and two resistors. So if that mid cone behaves like the JW then the crossover may well be three elements and no inductor.
The other interesting angle is that Ted Jordan was a consultant to Elac for a while some years ago.
I would love to get my hands on a couple of those drivers.
